Solid Oxide Fuel Cell Sealing Gasket

At Kriloha Ltd., we recognize that the integrity of the hydrogen economy depends on the strength of its smallest components. Our Solid Oxide Fuel Cell (SOFC) Sealing Gaskets are our engineered answer for “Ultra-High-Temperature-Containment” and “Molecular-Isolation”. As a premier global provider of advanced industrial seals, Kriloha has developed a hydrogen-specific barrier that balances mechanical invincibility with the thermal agility required for the clean energy transition.

The engineering of our SOFC series is based on Thermal-Dynamic Integrity. By utilizing specialized glass-ceramic and mineral-reinforced composites, we create a seal that conforms to the microscopic imperfections of the fuel cell plates. At Kriloha, we verify that our gaskets remain non-reactive with the delicate catalysts and electrolyte materials in the stack, ensuring peak voltage output over thousands of hours of service.

Manufacturing these gaskets involves strict Purity and Expansion Calibration. We ensure the material composition is optimized to survive the “Redox-Swing” (simultaneous exposure to fuel and air) without delaminating. Whether you are developing a next-generation electrolyzer or a stationary power plant, Kriloha SOFC Sealing Gaskets provide the mechanical durability your facility demands. By choosing Kriloha Ltd., you are investing in a “Hydrogen-Ready” technology that secures the efficiency of your highest-value energy assets.

Primary Use Cases

- Stationary Power Plants: Essential for large-scale SOFC stacks providing decentralized, high-efficiency green energy.
- Hydrogen Electrolyzers: Used in high-temperature steam electrolysis (HTSE) to produce green hydrogen.
- Combined Heat and Power (CHP): Providing reliable containment for residential and industrial fuel cell units.
- Marine & Aerospace Propulsion: Supporting the transition to carbon-neutral transport through durable, high-heat hydrogen containment.

FAQ's

1. Why is electrical insulation important in an SOFC gasket?
Because SOFC stacks consist of multiple cells in a series, the gasket must act as a dielectric barrier to prevent electricity from jumping between plates, which would cause a short circuit and stack failure.

2. How does the gasket handle hydrogen’s small molecular size?
Kriloha utilizes high-density material structures and specialized binders that transition at operating temperatures to fill all leak paths, creating a hermetic-standard barrier against hydrogen permeation.

3. What happens if the gasket CTE does not match the fuel cell?
If the gasket expands faster or slower than the ceramic fuel cell plates during heat-up, it creates massive mechanical stress that can lead to “stack-cracking,” resulting in immediate gas leakage and failure.

4. Can these gaskets handle fuels like methane or syngas?
Yes. While optimized for hydrogen, our SOFC gaskets are chemically stable in the presence of reformed natural gas, syngas, and ammonia.

5. Are custom thicknesses available?
Yes. To ensure a perfect fit for specific stack designs and tolerance requirements, Kriloha provides these gaskets in precision thicknesses ranging from 0.2mm to 1.5mm.
